Bria by Counterpath or other SIP clients for Iphone 4

Hi,

Can you recommend some good settings for my Bria sip client by Counterpath, please ?

I used to have an Android phone and my pbxes.org account worked very well with SIP Droid client.

I'm wondering how should I configure the Bria client to behave similar to SIP Droid, what settings should I use ?

Can you help please ?

Also if you think I know other sip clients that work better on Iphone with pbxes.org, please let me know.
